Contact the SWRC Research Leader, Dr. Mark Nearing at 670-6380 x152 or firstname.lastname@example.org. Mailing address is USDA ARS SWRC, 2000 E. Allen Rd., Tucson, AZ 85719 and web address is http://www.tucson.ars.ag.gov/ . The SWRC Quarterly is on—line at http://ars.usda.gov/News/News.htm?modecode=53-42-45-00.
The Southwest Watershed Research Center conducts long-term research of soil, water and climate processes to better understand interactions with plants, animals and humans as a basis for management of semiarid watersheds. SWRC develops new technologies for land managers, including remote sensing, computer-aided decision tools, and ecosystem models.
